Device for applying and removing nail polish

ABSTRACT

A device for applying or removing nail polish or nail art has a replaceable cartridge with a distal end removably coupleable to a proximal end of a handle. The cartridge has a reservoir that contains a liquid, such as nail polish or nail polish remover and a flow control member (e.g., valve) actuatable to allow flow of the liquid out of the distal end of the cartridge. The handle has a flow path therethrough that extends between its proximal end to an applicator implement (e.g., brush, sponge) attached to its distal end, the flow path in fluid communication with the flow control member when the cartridge is coupled to the handle. Selective actuation of the flow control member by the user (e.g., by squeezing the cartridge) allows fluid to flow out the reservoir and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.

DETAILED DESCRIPTION

Disclosed herein are several embodiments of a device (e.g., tool) forapplying and/or removing nail polish and/or nail art (e.g., applicatordevice). The device can be handheld. In some embodiments, the samedevice can be used for application of one or more substances (e.g. nailpolish, paint, glitter, nail art) as well as for the removal of said oneor more substance (e.g., via application of nail polish remover). Theapplicator device can have shapes other than the shapes described below.The applicator device can be made of any suitable material (e.g.,plastic, metal, etc.). The applicator can be made via using a suitableprocess, such as molding, casting, etc.

FIGS. 1-8 shows an applicator device 100 for applying a substance (e.g.,nail polish, nail art, nail polish remover) to a nail (finger or toenail) of a user's finger(s) and/or toe(s). The device 100 can haveextend between a proximal end 2 and a distal end 4. The device 100 has areservoir 10 at the proximal end 2, an applicator head 60 at the distalend 4, and a handle 40 interposed between the reservoir 10 and theapplicator head 60. Optionally, a cap 80 can removably cover theapplicator head 60.

The reservoir 10 can hold a substance (e.g., nail polish, nail polishremover, nail art, etc.) that can be delivered through the handle 40 tothe applicator head 60 for application on a user's finger and/or toenails. Optionally, the reservoir 10 can be in a detachable cartridge 20that removably couples to a proximal end 42 of the handle 40, as furtherdescribed below. Alternatively, the reservoir 10 and handle 40 can be asingle piece (e.g., monolithic, seamless piece). Optionally, the head 60can removably couple to a distal end 44 of the handle 40, as furtherdescribed below. Alternatively, the handle 40 and applicator head 60 canbe a single piece (e.g., monolithic, seamless piece). In one variation,the reservoir 10, handle 40 and head 60 are a single piece (e.g.,monolithic, seamless piece). In another variation, at least one of thereservoir 10 and applicator head 60 are removably coupleable to thehandle 40. In another variation, both the reservoir 10 and applicatorhead 60 are removably coupleable to the handle 40. Optionally, thereservoir 10 is refillable (e.g., via a removable cap, or via the flowcontrol member 30) by a user.

As best shown in FIG. 7 , in one variation the reservoir 10 is definedin a detachable cartridge 20 that removably couples to the proximal end42 of the handle 40. The cartridge 20 optionally has a contoured bodythat extends between a proximal end 22 and a distal end 24. Optionally,the proximal end 22 is curved and the distal end 24 has an opening 25sized to receive a lip 43 of the proximal end 42 of the handle 40. Thecartridge 20 optionally has a contoured (e.g., concave) top surface 26and a contoured (e.g., convex or domed) bottom surface 28 thatadvantageously allows a user to comfortable hold the cartridge, on itsown or when attached to the handle 40. Advantageously, the contoured(e.g., concave) top surface 26 can optionally receive the user's thumbthereon and the contoured (e.g., convex, domed) bottom surface 28 canoptionally receive one or more of the user's index, middle and ringfingers thereon, allowing the user to comfortably hold the cartridge intheir hand (e.g., with the index, middle and/or ring fingers flexed sothat the fingers contact a greater surface area of the bottom surface28). Additionally, the curved proximal end 22, can optionallycomfortably fit against the user's palm while holding the cartridge withtheir hand.

Optionally, the cartridge 20 removably couples to the handle 40 via apress-fit connection. In another variation, the cartridge 20 canremovably couple to the handle 40 via a threaded connection. In stillanother variation, the cartridge 20 can removably couple to the handle40 via a key-slot connection. In still another variation, the cartridge20 can removably couple to the handle 40 via a snap-fit mechanism; forexample, one of the distal end 24 of the cartridge 20 and the proximalend 42 of the handle 40 can have a ridge or protrusion that snaps orclips into a groove or recess on the other of the distal end 24 of thecartridge 20 and the proximal end of the handle 40.

Optionally, the cartridge 20 has a window 31, allowing the user to viewthe inside of the reservoir 10. The window advantageously allows theuser to readily identify the contents in the reservoir 10 (e.g., thecolor nail polish, type of nail art, etc.). Additionally, the window 31allows the user to readily identify the level of fluid in the reservoir10 and determine whether its contents are almost depleted such that achange in cartridge will be required.

With continued reference to FIG. 7 , the distal end 24 of the cartridge20 can have a recess 29 that is at least partially defined by theopening 25, and can have a flow control member 30 disposed in the recess29. Optionally, the flow control member 30 includes a flow control valve(e.g., one-way valve, needle valve, check valve, flap valve) thatselectively allows the liquid (e.g., nail polish, nail art, nail polishremover) to flow from the reservoir 10 through the flow control member30 and into the handle 40, as further described below. For example, theflow control member 30 can be made of a flexible material (e.g., rubber,plastic) and have one or more walls with a flap valve defined therein sothat when the cartridge 20 is squeezed, the flow control member 30 isflexed and the flap valve opens to allow flow from the reservoir 10therethrough, and when the cartridge 20 is not squeezed the flow controlmember 30 can unflex to its default orientation with the flap valveclosed to inhibit flow from the reservoir 10. Optionally, the flowcontrol member 30 can be moved from a closed position that inhibits flowfrom the reservoir 10 to an open position that allows flow from thereservoir 10. Optionally, the flow control member 30 is spring loadedand biased toward the closed position. Optionally, when the cartridge 20is coupled to the proximal end 42 of the handle 40, a feature in thehandle can press against the flow control member 30 to move it to theopen position to allow flow of liquid from the reservoir 10 into thehandle 40. In another variation, the flow control member 30 can includea button that can be pressed by a user, or pivotable lever that can bepivoted between two or more positions by the user, or slidable tab thatcan be slid between two or more positions by the user, on one of thecartridge 20 and handle 40 that can be selectively actuated by the userto open or close the reservoir 10 to fluid flow. In one variation, anactuator (e.g., on the handle 40) can be actuated (e.g., depressed,slid, pivoted) to eject the cartridge 20 from the device 100.

Optionally, the flow control member 30 can have a flow metering controlthat allows a predetermined amount of fluid to flow from the reservoir10. In one variation, the flow control member 30 can include a checkvalve or one-way valve or flap valve that can be actuated by the user.For example, the user can squeeze the cartridge 20 (e.g., press on thetop surface 26 and bottom surface 28 with their fingers), which cancause a flexible check valve or one-way valve to one to allow fluid flowfrom the reservoir 10 (e.g., as long as the cartridge 20 is squeezed).Once the user stops squeezing the cartridge 20, the flexible check valveor one-way valve can move to a closed position to disallow further flowfrom the reservoir 10 (e.g., until the cartridge 20 is squeezed again).

With continued reference to FIGS. 1-8 , the handle 40 optionally has acontoured body that extends from its proximal end 42 to its distal end44. The handle 40 has a top surface 46, at least a portion of which isoptionally contoured (e.g., concave) and has a contoured (e.g., convexor curved) bottom surface 48. Advantageously, the top surface 46 of thehandle aligns with the top surface 26 of the cartridge 20 to provide asubstantially continuous surface (e.g., a continuous surface thatsubstantially defines a circular surface, as shown in FIG. 5 ).Similarly, the bottom surface 48 of the handle aligns with the bottomsurface 28 of the cartridge to provide a substantially continuoussurface (e.g., a continuous surface that substantially defines a domedsurface, as shown in FIGS. 3-4 ). Accordingly, when assembled together,the cartridge 20 and handle 40 advantageously provides a contoured bodythat is easy and comfortable for the user to hold (e.g., while applyingnail polish to a nail of the user or a different person) and thejunction or transition between the cartridge 20 and handle 40 issubstantially smooth to inhibit discomfort to the user or potentiallycause the user to inadvertently push or pry the handle 40 away from thecartridge 20, inadvertently decoupling them. As best shown in FIGS. 3and 5 , the cartridge 20 can have a maximum width W1 that is greaterthan a maximum width W2 of the handle 40. Optionally, the handle 40 hasa conduit or flow path 49 that extends between the proximal end 42 anddistal end 44 of the handle 40. The conduit or flow path 49substantially aligns with the flow control member 30 of the cartridge 20to receive liquid from the reservoir 10 therethrough. Accordingly, oncethe cartridge 20 is coupled to the handle 40, the liquid in thereservoir 10 can flow to the distal end 44 of the handle 40 via theconduit or flow path 49.

With reference to FIG. 7 , the applicator head 60 optionally includes asupport body 62 attached to the distal end 44 of the handle 40, and anapplicator implement 64 attached to the support body 62.

Optionally, the applicator head 60 can be removably coupled to thedistal end 44 of the handle 40 (as shown in FIG. 8 ), allowing differentapplicator head 60 (e.g., having different types applicator implements64, different widths of applicator implements 64, different lengths ofapplicator implements 64, etc.) to be coupled to the handle 40 tocustomize the device 100 and its operation. Optionally, the head 60removably couples to the handle 40 via a press-fit connection. Inanother variation, the head 60 can removably couple to the handle 40 viaa threaded connection. In still another variation, the head 60 canremovably couple to the handle 40 via a key-slot connection. In stillanother variation, the head 60 can removably couple to the handle 40 viaa snap-fit mechanism; for example, one of the distal end 44 of the head40 and the support body 62 can have a ridge or protrusion that snaps orclips into a groove or recess on the other of the distal end 44 of thehead 40 and the support body 62.

In FIG. 7 , the applicator implement 64 is a brush having a plurality ofbristles. In another variation, the applicator implement 64 is a sponge.However, the applicator implement 64 can have other forms (e.g., a pen,a stamper tip for applying stamped designs, a striper tip for applyingstripes, a dotter tip for applying dots) that can optionally beremovably coupled to the distal end 44 of the head 40 as desired toallow a user to create (e.g. draw) nail art designs on their finger ortoe nails. In some variations, the applicator head 60 can beinterchanged while the cartridge 20 is loaded (e.g., coupled) to thehandle 40. In other embodiments, the applicator head 60 can beinterchanged prior to coupling a cartridge 20 to the handle 40.

The applicator head 60 can have a conduit or flow path 66 (See FIG. 6 )that extends through the support body 62 to the applicator implement 64.The conduit or flow path 66 substantially aligns with the conduit orflow path 49 in the handle 40, so that the liquid (e.g., nail polish,nail art, nail polish remover) that flows through the handle 40 from thereservoir 10 flows to the applicator implement 64 (e.g., brush, sponge)via the conduit or flow path 49 in the handle and the conduit or flowpath 66 in the applicator head 60. Accordingly, once the cartridge 20 iscoupled to the handle 40, and the flow control member 30 is actuated asdescribed above, the liquid in the reservoir 10 can flow to theapplicator implement 64 for application by the user (e.g., to a fingeror toe nail).

FIG. 9 shows one embodiment of a kit 200. The kit 200 can include a casewith one or more cartridges 20, each having a different fluid (e.g.,color nail polish, nail polish remover, nail art) in its reservoir 10,one or more handles 40, and one or more applicator heads 60 with atleast two different applicator implements 64 (e.g., sponges, brushes,pens, stamper, dotter, stripper). In some variations, the kit 200 canhave only cartridges 20, or only applicator heads 60. A user can thenassemble the device 100 by coupling one of the cartridges 20 and one ofthe applicator heads 60 to the handle 40 to assemble the applicatordevices 100, such as the applicator devices described above. The kit canalso include one or more (e.g., a plurality) of cartridges 20.

Advantageously, the removable and replaceable cartridges 20 allow theuser to utilize a variety of different nail polishes utilizing the samehandle 40 and/or applicator head 60 to creatively apply differentdesigns to a finger or toe nail in one sitting, therefore making theprocess more efficient and avoiding stains (e.g., from dripping nailpolish in conventional nail polish bottles). Additionally, the systemdescribed herein advantageously allows the user to readily couple anddecouple different cartridges (having different color nail polish orart, such as glitter) with a handle having different applicatorimplements (e.g., brush tip, sponge tip, stamper tip, striper tip,dotter tip) in one sitting to apply complex creative designs to a user'snails, making the process more efficient. In one variation, differentapplicator implements can be removably coupleable to the handle, so thatthe user can customize the applicator device utilizing differentapplicator implements and different cartridges as required by thedesired nail art design.
